i like it a lot, a lot, but it has problems, the mine cubes stop working, there's graphical glitches when the plasma cube and EM cube shoot
the graphics are gorgeous, the sounds feel good and the game keeps you busy and immersed-
but the difficulty can be downright impossible if you dont get the right upgrades!
TIPS to save you time and nerves:
-try to always get as many stars as possible
- upgrade lasers, freeze ability and healing cubes ASAP
- then do the plasma cube, then the shield ability, use it often
- later on upgrade Gauss, anti-air, EMP (important!), factory
- abilities : EMP, Ray of death, Rocket Storm in that order
